Stylevars & css variables not found

[angedelamort]

So, as the usual question on this forum, where can I change this or that. I've almost managed to change everything to my taste, but those 5, I just don't know how to find/fix them.

stylevars_01.png: For this one, I just want to change when the highlight is there and only for those one in that menu.

// without press search for:
.navtabs li.selected li:hover a.popupctrl

// while pressed, search for:
.navtabs li.selected li:hover a.popupctrl.active

stylevars_02.png: For this one, other than hardcoding it in the template, I'm not able to change it via the css.

.popupbody li > a, 
.popupbody li > label

stylevars_03.png: Same as the previous one. I suppose they are related somehow.

// I decided to change it in the template:
.forumsearch.popupmenu .popupbody

stylevars_04.png: I don't know if it's because of the gradient, but it seems that it doesn't really work well when selecting a thread via the checkbox. If I cannot do anything about it, I'll leave it like that.

stylevars_05.png: This one is funny. I don't remember changing anything about that css. But I've changed numerous stylevars. I've tried different things and the icons are just not in the frame. When I compare the code with the original, I've got the same thing. Some good pointer on how I can fix that would be greatly appreciated.
Fixed: I don't know why, I just rechecked and it seems fine now for no reason.

Thanks in advance and I'll try to update this message when solution arrives.
